Hi !
When I expand a folder in treectrl.exe sample the icon associated to
the root item is not properly refreshed. You still see the old image
(closed folder) "below" the new image. The problem disappears when
you for example resize the window or it gets refreshed. Is that a
problem in the sample or in wxWindows or in comctl32.dll ?
I use the version 5.80.2014.516.
I get the same problem on NT SP6 and 98 SE.

can you reproduce this in the treectrl sample? if so, please attach a screenshot
here so that I could see how it looks like
